Validate Restriction

apply_filters( 'vikappointments_before_validate_service_restriction', bool|null $valid, object $restr, string $checkin, bool $add )

Fires while checking whether the user is allowed to book a service according to the specified restriction criteria.

Description 

This hook can be used to alter the validation of a booking restriction.

Parameters

$valid

(bool|null)  It is possible to return FALSE to consider the restriction as applied and prevent the customer from booking the selected service. Otherwise it is possible to return TRUE to consider the booking process valid without relying on the default validation process applied by the system. Return NULL to fallback to the default behavior.

$restr

(object)  An object holding the restriction details. 

$checkin

(string)  The UTC check-in date in military format (Y-m-d H:i:s).

$add
